Application filed February 4, 1928, Serial No. 251,984 and in France November 10, 1927..

The present invention relates to a new construction for mctallic flooring plates,

which is chiefly adapted for the flooring of factories. The said flooring plates are adapted connected together in such manner'that the flooring will not suffer deformation under the simultaneousv action of the weight of heavy machine pieces, and of the heating to which the said flooring may be subjected in certain cases. i

The rigidity of flooring plates and of their connecting members is very simply obtained by the treatment of the steel plate of the 1 proper thickness by the stamping or pressing process, and this operation will simultaneously produce the stiffening ribs or corrugations on the plates as well as the'portions for attaching the auxiliary assembling pieces. The said flooring is constructed according to the principle of ceramic tiling with octag-' onal tiles and small filling plates, but in my said device the filling part consists of two concave piec'esfitted together, whereof one is placed at the upper part and the other at the lowerpart' of the flooring late, said concave pieces being in contact at t eir edges with the cut-off corners of the. four plates which coincide at 'a given place. The whole device is held in place by a suitable bolt.

The appended drawings show byway of example an embodiment of the invention. Fig. 1 is 'plan' view of a flooring plate, showing also the commencement of the three and the assemblingarrangement for the said flooring plates, Fig. 2 is v a section on the line AA of Fig. 1. Fig:

3 is a sectional view showing the cut-off corners. Fig. 4 is a sectional view of the as- 40 sembled device on the line B-B of Fig. 1.-

square sheet metal plate 1, which is .pressed into the form of an inverted concave piece.-

as to substitute for the square, an octagon comprising four small sides 3'. The drawings also show, upon the part connecting the upper face and the small side 3, an additiona1 recess 4. i

The square. space which is thus formed between 1 the four dplates meeting at a given angle,-is adapte to receivethedevice conto. form a flooring whose parts are- Each of the flooring plates c'onsists of a.

and economical auxiliary members sisting of two pressed sheet metal concave members 5 and 6... One of the said members 5 fits into the said space, since its flanged edges coact with the edges of the recess 4. The second concave member 6 is disposed 61) upon the lower face of the plate, and it fits upon the outside of the small sides 3. The members 5 and 6 are pierced with central holes for the insertion of the assembling bolt 8. When drilling the concave member 6, 66 there are detached and turned down two or four tongues 9, between which is held the bolt head '10, thus. preventing it from turning, so that the nut 11 may be turned to hold the device together. V 70 The flooring which is thus formed may undergo slight deformations, but without any prejudice to its continuity. It can be very simply manufactured, since all the pieces are obtained from sheet metal by the 7 pressing process. A sufiicient space is allowed between the several plates in order to permit the expansion of the pieces at high temperatures.

Obviously, the details of construction herein described are given solely by way of example, and they may be varied without departing from the principle of the invention, this consisting essentially in the use of octagonal facing plates consisting of pressed sheet metal, the four sides of the square space formed at each corner of the plate being held between two pressed metal concave members of suitable shape, with the use of a clamping device. I 1

The use of the said flooring plates is not limited to foundries or machine shops, but such plates can be used in general building construction.

While it is true that the pressing process on as applied to metal plates is the most reliable for the manufacture of all the pieces of the flooring, other means. may be employed for the manufacture of the such-as the concave com necting members.

Claims:

1. In a metallic flooring for factories, pressed metal plates of. sqare form provided with four small sides at the corners completing an octagonal form, a downward flange on the edges of the metal plates and recesses on the surface of the plates in front of the small sides, an upper concave member of square ,form fitting into the recesses of four adjacent plates, an under concave member underneath engaging the flanges of the same adjacent plates, and means for clamping together the two concave members.

2; In a metallic flooring for factories as claimed in claim 1, pressed metal plates of square form provided with four small sides at the corners completing an octagonal form, a downward-flange on the edges of the metal '10 plates and recesses on" the surface of the plates in front of the small sides, an upper concave member of square form fitting into the recesses of four adjacent plates, an under concave member underneath engaging the clampin together the two concave members .the hea -of which is inserted between the downturned tongues.

In testimony whereof I afiix my signature,
